Exactly. Machine guns invalidated cavalry charges, but we ended up in a trench war just trying to create a break in the trenches long enough to get the cavalry through. Tanks invalidated trench warfare, but the French built an impregnable defensive line along the border that would make them invincible in the next trench war.
And it's fascinating seeing the comments here saying "nah, this won't change anything" when it already is changing things.
And yes, the blurring of the lines is a problem. As others have pointed out, hiding drones in civilian populations is easy.
I was at an SMS aggregator before joining Twilio back in the day.
At the SMS aggregator, it took $10k to get started, $1k/month for a short code, and $0.1/message.
When I discovered Twilio and found it took $0 to get started, $1/month for a long code, and $0.01/message, the world changed.
It became easy enough to build yourself, fast enough to experiment with, and cheap enough to fail. I see the same thing happening here but with lives on the line.
